The cathedral of Turku was the center of the cult of Saint Henry, and naturally the cultural center of the bishopric.

From the 5th century the city was a bishopric, and during the Lombardic kingdom it was a royal city and had several privileges.

André Ernest Modeste Grétry ( 8 February 1741 24 September 1813) was acomposer from the Prince Bishopric of Liège (present day Belgium), who worked from 1767 onwards in France and took French nationality.
